278878 divided by 90 
We're looking to find how many times 90 goes into 278878.

Moving on to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 90

Let's proceed to step 2:
90 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 90

On to step 3:
90 can be fit into 278 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 270 from 278 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 90

On to step 4:
90 can be fit into 88 0 times, resulting in a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 88, we end up with 88.
Grab the next digit (7) from the dividend, add it to 88, then carry on: 887 / 90

Advancing to step 5:
If we divide 887 by 90, we get 9 and a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
If we subtract 810 from 887, we get 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 90

Going ahead to step 6:
If we divide 778 by 90, we get 8 and a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 3098.0
Subtract 720 from 778 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
90 can be fit into 580 6 times, resulting in a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 3098.6
Subtract 540 from 580 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
400 divided by 90 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 3098.64
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 3098.644
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 3098.644, and the remainder is 0.004.
